1. An antenna module which is mountable on a surface of a printed circuit board which contains an electrically conductive layer that constitutes a ground plane for the antenna module,
wherein the antenna module is embodied as a planar body having a top surface and a bottom surface, wherein the bottom surface is configured to be mounted on the printed circuit board and the top surface is facing away from the bottom surface, wherein the planar body is a layered structure comprising:
a central planar layer of dielectric material;
a first circuitry of electrically conductive material on a bottom side of the central planar layer;
a second circuitry of electrically conductive material on a top side of the central planar layer;
a multitude of vias of electrically conductive material that extend through the central planar layer from the bottom side to the top side thereof;
wherein the antenna module is an electrically active component and the first circuitry includes a feeding strip of electrically conductive material that is connected to at least some of the vias,
wherein the second circuitry is formed by a radiation layer of electrically conductive material which radiation layer is electrically connected to at least some of the vias, which radiation layer has outer edges that constitute a periphery of the radiation layer,
wherein the radiation layer is provided with multiple slots that divide the radiation layer into sections that are interconnected to each other as branches,
wherein the slots are provided in the radiation layer in such a way that each of the slots extend from an outer edge of the radiation layer, and
wherein the radiation layer includes one or more isolated sections which are delimited by one or more slots and which are not interconnected with other sections of the radiation layer, wherein the isolated sections function as a passive component when the antenna module is in operation.
